Martha is making a recipe that requires 2/5 of a cup of sugar. She only has 1/3 of a cup of sugar at home, though. What fraction of the recipe can Martha make with the amount of sugar she has?
1 answer
Martha has 1/3 of a cup of sugar, which is less than the 2/5 of a cup required by the recipe. Thus, she can only make a fraction of the recipe that is 1/3 / 2/5 = 1/3 * 5/2 = 5/6. Answer: \boxed{\frac{5}{6}}.
